VALVE Mncnnnrsivr.

Application led January 12,1921. Serial No. 436,680.

To all whom it may concern:

Be it known that I, FRED GRUBER, a citizen of Germany, residing at Norfolk, county of Norfolky and State of Virginia, have invented certain new and useful Improvements in Valve Mechanism, of which the following is a specification.

This invention relates to improvements inv internal combustion engines, particularly in the valve mechanism of such engines for controlling the intake and exhaust of the motive fluid.

It is the principal object of the invention to provide a valve mechanism in which the entire series of valves for an engine of any number of alined cylinders are mounted transversely disposed to the cylinder block.

A. further object of the invention is the provision of a valve mechanism in which the valves are worked by means of plungers which are aotuatedby the intermediary of a plurality of actuating plates operated by the cam shaft.

Other obj ects and advantages of my invention will become more fully apparent from the following description, reference being had to the accompanying drawings,and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the drawings,-

Figure 1 is a diagrammatic side view of an internal combustion engine provided with a valve mechanism constructed according to the present invention.

Figure 2 vis a top plan view thereof.

Figure 3 is a transverse section on line 3-3 of Figure 2.

Figure 4 is a transverse section on line 4 4 of Figure 2.

Figure 5 is a longitudinal section alongy line 5-5 of Figure 2.

Figure 6 is a section along line 6-6 of Figure 5, and

Figure 7 is a detail view of the actuating plate system.

F igure'8 is a fragmentary top plan view, partly in section of the valve operating mechanism.

In the drawing, 10 indicates the crank case of a four cylinder combustion engine, and 11 the cylinders thereof. The carburetor is indicated at 12. The connections to the intake manifold are designated at i3 and those to the exhaust manifold 14'and are contained in a block 15 on top ofthe cylinder block.

As shown, the crank shaft 16 carries at its outer end the fly wheel 17, and behind the same a bevel'gear 18 in mesh with a bevel gear 19 at the end of a shaft or link 2O carrying a bevel gear 21 at its other end in mesh with bevel gear 22 of the cam shaft 23 journaled in a block 24 in the rear of the cylinder block and adapted-to operate in the well known manner, the actuating plates 25 hingedly secured at their upper ends to a shaft 26 located near the upper end of the block 24 and j ournaled in the side walls thereof.

As shown in Figure 8 the valves 28 are actuated in pairs by the crank arms of shaft 23.

rIhese plates operate plunger-s 27 horizontally arranged in block 24 and engaging with their outer freel ends'the stems 28 of valves 29 of the piston type which enter channels 30 in the rear of the block 15, the valves being yieldingly held in closed position by means of coiled compression springs 31 which surround the stems 28 projecting from the rear of block 15 and bear between collars 32 on the stems and bushings 33 on the rear face of the block 15. Suitable channels 34 are provided in the block 15 for the reception of the spark plugs.

The intake valves, one of which is shown closed in Fig. 4, will be opened during the intake stroke by the operation of their stems 28 by the cam shaft under compression of springs 31 and the charge will be exploded by the active spark plug in channel 34 to operate the pistons. After the ignition and explosion, the intake 'valves will be closed by the expansion of their springs 31 as the cam shafty will have ceased to operate the stems 28, while the exhaustvalves will then be opened bythe operation of their stems by the cam shaft to compressA their springs 31 as shown in ig.` 3. l

The channels'l3 and 14v areprovided in the block 15 for allowing a removal of the valves for grinding and cleaning purposes. rlille-channels 3 and 14 are closed'by screw plugs 13 and 14 respectively.

'It will be apparent that by removing the blocks 24 and 15 the entire valve mechanism may be readily lifted from the engine, and that changes may be made in the general arrangement of the parts and construction the rear off said first blocks, a plurality of plungel's horizontally disposed in said third block-anda Shaft longitudinally disposed in said third block7 a `plurality lof actuating plates hingedly secured at their vupper ends to` said shaft .andadapted to be operated by the cam shaft of the engine to operate said .,plungers for operating said stems and valves, i

In testimony whereof I have affixed my signature.

FRED GRUBER.
